Abstract:This paper introduces a new polygon project based on the HYPER GRAPH logi- cal structure and on the relational data base "physical structure" in which the structure of the polygons located on a plane layer is tree construction. they have their own class and dynamic character that permit the tree continuously to grow. which is similar to dividing area in reality. Based on the above the node match is given a new sense and the definition of the corresponding process of the data input and the search is also given. The process of data input is simplified and input quantity is greatly decreased. the sear- ch of a polygon can be made by selecting the "father's series polygons".
Keywords:GIS  Hypergraph Relational data base  Node topological data match  Father's series polygons
